Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of PTGX price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: September 14, 2023
End date: September 6, 2024
a = -1.3525
b = 0.0028
s = 0.1019
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × 0.0028) – 1
= 177.69%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.1019) – 1
= 50.33%

Top border of price channel:
Exp(Y1,011)
= Exp(a + b × X1,011 + 2 × s)
= Exp(a + b × 1,466 + 2 × s)
= Exp(-1.3525 + 0.0028 × 1,466 + 2 × 0.1019)
= Exp(2.9534)
= $19.17
Bottom border of price channel:
Exp(Y1,011)
= Exp(a + b × X1,011 – 2 × s)
= Exp(a + b × 1,466 – 2 × s)
= Exp(-1.3525 + 0.0028 × 1,466 – 2 × 0.1019)
= Exp(2.5458)
= $12.75

= Exp(3.9552)
= $52.21
Bottom border of price channel:
Exp(Y1,257)
= Exp(a + b × X1,257 – 2 × s)
= Exp(a + b × 1,824 – 2 × s)
= Exp(-1.3525 + 0.0028 × 1,824 – 2 × 0.1019)
= Exp(3.5475)
= $34.73
